Charlie

Charlie

Charlie is a bright and adventurous five-year-old with shaggy brown hair and his signature overalls, always ready for his next discovery.

He loves building, sketching invention ideas, and experimenting to see how things work. Whether creating a small model or testing a new design, Charlie enjoys solving problems and learning through trial and error.

Curious and brave, he enjoys exploring new places, diving with his parents, and uncovering hidden details in the world around him. His emotions are lively and honest—he laughs, wonders, gets frustrated, and quickly turns that energy into new ideas.

Thoughtful beyond his age, Charlie often helps others and approaches challenges with creativity and care.

Goals & Learning Outcomes

Predictions & Outcomes
Kids practice forming a hypothesis before observing.
Sorting & Classification
Grouping objects by sink/float builds early classification skills.
Pattern Recognition
Kids notice connections between an object's material, size, or shape and whether it sinks or floats.
Recording Observations
Using a simple chart introduces the idea of documenting results for comparison.

Science & Design Concepts

Density

Compares how much an object "weighs" for its size. Objects denser than water sink; objects less dense than water float.

Buoyant force

Water pushes up on every object placed in it. If that push is strong enough to support the object's weight, it floats; if not, it sinks.

Size vs Weight

A big object isn't always heavier "for its size" than a small one. Kids learn that size alone doesn't predict whether something sinks or floats — what matters is the material.

Shape and air pockets

Hollow or air-filled objects (like a closed bottle) float more easily because trapped air lowers the object's overall density.
